Having had the car that started this thread a few months now and (amazingly) for nearly 2000 miles, I find the 915 fine to use as long as I push the clutch pedal right to the floor, and to be fair, it does say to do this in the handbook. It's not a shift that likes lightning fast changes but can be used swiftly and yes, with two fingers quite easily.
The only time I have trouble, usually going into third, is when I am not concentrating on the shift and been lazy with the clutch.
